To alt whom it may concern:

Be it known that 1, CHARLES KELLY, of Passaic, in the county of Passaic and State of New Jersey, have inventedcertain new and useful Improvements in Acetylene-Gas Generators, of which the following is a full, clear, and exact description. a i

The object of the invention is to provide oer tain new and useful improvements in acetylene-gas generators whereby the hydrate of lime is removed automatically from the generator to keep the flow of the'water from the tank to the generator unobstructed, and in case of any abnormal pressure of gas the latter is vented to theopen air' before the'water seal in the tank is broken. I i

The invention consists of novel features and parts and combinations of the same, as will be described hereinafter, and then pointed out in the claims. i

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures. 1

Figure l is a side elevation of the improvement, with parts in section; i Fig. 2 isa plan view of the same,'and Fig. 3 is an enlarged transverse section of part of the generator on the line 3 3 in Fig. 1. i

The improved acetylene-gas generator is provided with a holderA and a diaphragm B for dividing the holder into an upper compartment O and a lower compartment 1). In the diaphragm Bis arranged a downwardlycxtending pipe E, terminating at its lower end a short distance from the bottom of the lower compartment D, so that water can pass through said pipe E up into the compartment G in case of abnormal pressure.

From the water-compartment I) lead one or more main pipes F to a chamber G, arranged on a gas-generator G, eaehpipe F being provided with a valve F for controlling the flow of the water from the compartment D into the chamber G, connected with the interior of the generator, so tliatthe water can rise in the generator to the calcium earbid contained in the basket H, held in the generator. The gas generated by the contact of the water with the calcium carbid passes from the upper portion of the generator through a pipe I, having a valve 1', and continuing in a coil 1 arranged in the upper portion of the compartment 0, the upper end of the coil 1 extending, asat 1 through the top of the holder A to a governor J, of any approved construction, for controlling the amount of gas passing to the service-pipe K.

The bottom G of the generator G is inclined downwardly to the chamber G and opens into the latter at the lower end of said bottom, so that water can pass from the chamber into the lower portion of the gener ator, said chamber also opening into a set tling-chamber G formed below the bottom G2 in the extreme lower portion of the generator. Now it is evident that the hydrate of lime-that is,the residue left by the process of generating the gas by the water contacting with the calcium carbiddrops down on the bottom G and slides from the same in a downward direction into the chamber G and from the latter to the settling-chamber G in which it accumulates.

- The top of: the generator G is normally closed by a removable cover G held on a screw-rod G screwing in a yoke G, pivoted at G to the outside of the generator and provided with an arm G connected by a link L' with an arm L secured to the stem L of an outlet-valve L, leading from the lower hopper-bottomed end of the settling chamber G When the calcium carbid in the basket II has been used up and it is desired to replace the same, then the valve F is closed to shut off the water from the compartment D. The operator now screws the screwuod G upward to lift the cover G off its seat, and then the yoke G is swung over to the position indicated in dotted lines at the left in Fig. 1, so that the arm Gr swings upward and moves the link L and the arm L in a like direction to open the valve L, so that the residue accumulated in the settling-chamber G passes through the valve L to the outside, together with the waterin the generator. The basket H is now removed and refilled with calcium carbid and then replaced inthe generator, after'which the yoke G: is swung back to its normal position to bring the cover Gr over the top of the generator.

Now by serewin g the screw-rod G downward the cover is carried in a like direction and is finally seated on its seat on the top of the generator to securely close the latter.

By the arrangement described the hydrate of lime is discharged automatically from the generator proper into a suitable chamber and allowed to flow out of the latter upon automatically opening the valve L on removing the cover G as above explained.

By the arrangement described the flow of the water from the compartment D through the pipe F into the chamber G is not interrupted by the hydrate of lime, as the latter settles into the chamber G and leaves the passage for the water to the generator open. An air-vent pipe N extends into the watercompartment D, the lower end of said pipe being a short distance above the lower end of the diaphragm-pipe E, so that in case ex cessive pressure of the gas generated drives the water back through the pipe F into the compartment D and from the latter up the pipe E into the upper compartment 0 then the lower end of the pipe N is uncovered before the lower end of the pipe E is reached, so that the gas or air can readily pass up through the pipe N to the outer air before the water seal at the lower end of the waterpipe E is broken.

The pipe N is provided within the compartment O with a water-relief or branch pipe N, so that any water forced up the pipe N can readily drain back through the pipe N into the compartment 0 to leave the pipe N unobstructed for the ready passage of the air or gas through the pipe, as above described. The upper ends of the generators G are also provided with relief-pipes O, having check-valves 0.

It is understood that by the arrangement described the gas generated in the generator first passes up through the non-decom posed carbid, which dries the gas, and then the latter passes through the coil I which cools the gas previous to its passage to the servicepipe K. The amount of gas made is exactly in proportion to the consumption, as it is evident that if more gas is made than consumed the surplus gas will drive the water in the generator downward from the carbid and through the pipe F back into the compartment D,- as previously mentioned. cover G of each of the generators G can now be removed by automatically opening the of any water which may have been carelessly left in it, and at the same time the hydrate of I lime is discharged from the settling-chamber.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. An acetylenegas apparatus, provided with a generator for containing the calcium carbid and having an inclined bottom, a set tling-chamber below the said generator, and a water-inlet chamber connected with a water The supply and opening into the said generator directly above the inclined bottom thereof and into the said settling-chamber, substantially as shown and described.

2. In an acetylene-gas apparatus, a generator having a bottom inclined to one side, a settling-chamber below the inclined bottom of the generator, and a water-chamber arranged at one side of the generating and settling chambers and having its outer wall inclined downwardly, said water-chamber being connected with a water-supply and opening into the generating-chamber directly above the inclined bottom thereof and into the settling-chamber, substantially as and for the purpose set forth.

3. An acetylenegas apparatus, provided with a generator for containing the calcium carbid and having an inclined bottom, a set tling-chamber for the hydrate of lime and into which discharges said inclined bottom, an outlet-valve for the said settling-chamber, a removable cover for the said generator, and means for connecting the said cover with the said outlet-valve, to automatically open the latter upon opening the said cover to drain the water from the generator, substantially as shown and described.
